水下激光扫描系统中扫描轴系的调整分析

Analysis of Pyramid Reflector Adjusting in Under Water Laser Scaning System

本文简述了水下激光扫描成像系统的原理并建立了物方和像方坐标系,运用棱镜调整理论,分析了扫描轴系沿三坐标轴的平移Δx,Δy,Δz及转角Δα、Δβ、Δγ对出射光线偏转的影响,推导出了扫描轴系的转角Δβ、Δγ产生的出射光线绕y,z轴的像偏转公式。

The principle of under water laser scaning imaging system is discussed simply and reference frame of object and image is established. Scaning axis maybe have relative departure △x,△y,△z and angle △α、△β、△γ to the three frame axises. The effect of scaning axis upon reflecting axis during the process of scaning is analysed based on the theory of prism adjusting. The formla of image deflexion is received on condition that scaning axis have turned △β、△γ.
